Lecture 9 notes Volume and pressure • For a fixed volume of fluid, pressure depends on the volume of the space it occupies – Large space = lower pressure – Small space = high pressure – As the size of the space changes, so does the pressure – Apply this concept to heart chambers Pressure gradient: difference in pressures between 2 regions (P – P ) 1 2  Fluid flows from high pressure to low pressure o Pressure at first point will decrease; pressure at second point will increase o This holds true as long as the path is not blocked Volume and pressure  Volume of chambers change during a heartbeat  Also pay attention to
